RobynsVeil: I mentioned that you need familiarity with blender which means knowing how to work in blender, keyboard shortcuts and whatnot. Otherwise, it's "a bit" confusing.

I recommend going through CG Cookie tutorials first. There is an in-depth introduction to Blender in 3dBuzz as well, but, while it's free, it requires registration and currently unavailable for streaming: you have to download and unpack archives with videos. CG Cookie is much more convenient and has rigging and animation tutorials (not nearly as in-depth as "Humane rigging", though).

As for vertex groups and bones, you can rename them in blender after importing the model.
